And my experience in recordings of extremely high data rate:My HDD is capable of sequential write of 220 MB/s, while it starts to encounter I/O bottleneck at around 95 MB/s (no problem with a SSD), likely due to non-sequential writing caused by insufficient caching.

It appeared of necessity to allow the user to explicitly set the amount of memory allocated for caching.

We have tested with AVI, H264(NVIDIA NVENC), and PCM, the "Enable write caching on the disk" option enabled, but we were not able to create the recorded file broken issue.Regarding the website revision, we've forwarded it to our website development team.

Something may reach 800+ Mb/s...

An example:(though might not reach the above data rate... should be enough to reproduce the problem)4K (3840x2160) @ 30 FPS, car racing game (or anything with similar high motion).
